Highly sensitive DNA detection in gel: Using a unique combination of filters, the Dark Reader is at least as sensitive as a UV transilluminator for the detection of many dyes. For example, using SYBR Gold stain it is possible to see, by eye, less than 100 pg of DNA.

Detection of fluorophores in plastic
All our Dark Reader products, including the Hand Lamps, are particularly effective for viewing fluorophors in places where UV light cannot reach – through glass and plastic.

Detect fluorescently-transformed bacterial colonies
Using a DR transilluminator, the fluorescence from EYFP expression in bacterial colonies is easily detectable. Picking the correct colony has never been easier.

Real-time detection during gel electrophoresis
Adding Viridi stain to the agarose before running allows the DNA migration to be monitored during electrophoresis using a Dark Reader Hand Lamp.

Monitor protein expression in transgenic animals or plants
Our customers have used Dark Reader Hand Held Lamps to visualize fluorescence in fish, mice, sheep, corn, leaves, seedlings and silkworm coccoons!

Very sensitive protein detection in gels/membranes
The Dark Reader technology can detect as low as 2ng of protein with the use of SYPRO Ruby.

Dark Reader Technology can be used to detect many different fluorophors. In general, the ideal spectral characteristics for a `Dark Reader dye` are an excitation maximum between 420 – 500 nm and an emission maximum above about 520 nm.

The Dark Reader can also be effectively used to detect dyes that have maxima outside the above ranges. The only criterion is that at least a portion of the fluorescence excitation and emission fall within these ranges. Stated another way, the Dark Reader can be used to detect almost any dye excited in the visible range that does emit exclusively in the blue.
